3 Claims. (Cl. lill-391) This invention relates to a printers chase, and is particularly concerned with the provision of means for quickly locking a type form that will permit shifting of the type without removing the chase from the press,

Although ther structure `described herein may be advantageously used `for almost any printing press lockup because of the speed and security of its operation, it is particularly designed for use in connection with small forms,` such as imprinting. Often the same vtype may be used for various size sheets. The chase constructed in accordance with the present invention permits the type to be shifted, vertically and laterally, without` removing the chase from the printing press, thereby minimizing the setup time by eliminating guide changes. My improved chase also permits removal and replacement of type locked in the chase Without removal of the chase from the press, eliminating the use of furniture to fill the chase.

In accordance with the present invention a small chase is mountedin a larger chase which in turn is secured in a printing press. The smaller chase is slidable laterally in the larger chase and is held in any lateral position by a quoin. The smaller chase is also provided with a quoin to hold a type form laterally and with a vertically slidable cross arm to regulate the vertical position of the type form in `the small chase. The cross arm is particularly important in connection with the `printing of circulars where the subject `matter may be in the form of a solid plate positioned in `the small chase for successive runs of uniform size with a different name and address to be imprinted 'on different runs. A single line or more `of type bearing `the name andV address may be positioned against the plate ,in order Vto print the circular and the name and address simultaneously. It is a very simple matter to remove and replace the single line or more of type Without changing the rest of the set-up. lf the same circular or other form is to be printed on a sheet of ditferent size, the smaller chase may be moved laterally into the desired space for the new sheet, and the cross arm may be moved vertically and locked in a different position to adjust the vertical spacing of the printed matter relative to the new sheet.

The structure by means of which the above and other advantages of the invention are attained will be described in detail in the following specication, taken in conjunction with the accompanying drawings, showing a preferred illustrative embodiment of the invention, in which:

Fig. l is a plan view of a chase embodying the invention;

Fig. 2 is a plan view similar to Fig. l with the type omitted and portions of the large chase broken away to facilitate illustration of the relationship between the larger and smaller chase;

Fig. 3 is a cross sectional view, taken along the line 3-3 of Fig. 4; and

Fig. 4 is a cross sectional View, taken along the line 4-4 of Fig. 3.

Referring to the drawings, the larger chase comprises a rectangular frame 2 having transverse walls 3 and 4 2,785,629 .Patented Mar. 1,9, 19.57

and side walls 5 and 6. The sizeof the` larger chase` depends upon the area of bed ofthe printingv press, being usually `of therrnaximum Ysize the press will hold. When the amount of Vtypeis Ys uicient to substantially ill the larger chase it ispused inconventional manner. However, if the printing area is comparatively small, the conventional chase requiresa considerable amount of furniture to fill up the space not occupied by type.

in order to dispense with `the necessity of using an excessive amount of furniture when the printing area is small compared to `the area of the larger chase, I have provided a smaller chase 9 comprising transverse walls 10 and 11 parallel to walls 3` and 4 of the large chase, and side walls 12 and 13 parallel to side walls 5 and 6, Wall 10 is provided with an outwardly projecting `flange 14 engaging a groove 15 provided in the inner ezdge surface of wall 3. Wall 11 has a flange 16, similar to flange 14, engaging a groove 17 provided in a transverse bar 18V loosely securedrin parallel spaced relationship to -wall 4 by lmeans of splines 19 and 20. Walls 5 and6 are recessed adjacent the splines so that they may be removed when it istdesired to remove :the smaller chase. The splines t tightly in `the recesses (not shown) of walls 5 and 6 and willgnot be accidentally dislodged therefrom. The opposite ends of transverse bar 18 are bifurcated to fit over the splines to permit limited movement of the Vbar towards or away fromwall 4.

A pair of corner plates 21 and 22 maintains a minimum spacing between bar -18 and wall 4. A` quoin 23, positioned between wall4 and bar 18, is held against lateral movement by corner plates 21 and 22j. Quoin 23 is operable to move bar 18 away from Wall 4 into binding relationship with Wall 11` to prevent lateral movement of smaller chase 9 and to hold it in any desired lateral position within larger chase 2. A

The intereng'aging ilange and groove structure, which comprises the sliding lit between Bange 14 and groove 15 and between llange 16 and groove 17 may be reversed, if desired. For example, the transverse walls of the smaller chase may be grooved, and the appropriate surfaces of Wall 3 `and bar 18 may be provided with anges to fit in the grooves.

Smaller chase `9 is also provided with a quoin 24 engageable withone edge of a form of type 25. Quoin 24 is spaced from wali 12 by a lateral spacing bar 26 and both these members are held against longitudinal movemerit by corner plates 27 and 28. The quoin, as shown in Fig. 4, comprises a channel shaped member 29 having its sides fitting over a pair of juxtaposed bars 30 and 31. The end of bar 30 is notched to t -over the edge of corner plate 27, and its adjacent face -is wedge shaped, as indicated at 32. Pins 33, projecting from bar 30, it into notches 34 in the side of channel shaped member 29. The end of bar 31 juxtaposed against wedge surface 32 is tapered in the opposite direction, as indicated at 35. A pinion gear 36 is rotatably mounted in bar 30, and the adjacent surface of bar 31 is provided with rack teeth 37 engaging pinion 36. An aperture 38 provides access for a key (not shown) to engage pinion 36 to rotate it. Rotation of pinion 36 moves bar 31 relative to bar 3i) to move channel member 29 outward or to permit its retraction.

ice

VA pin 39 projecting from bar 31 fits in a slot 40 provided in the side of channel member 29. Quoin 24 is loosened to permit type form 25 to be inserted or removed and also to permit movement of the type form towards either wall 10 or l1 until it is properly opsitioned. The positioning of type form 25 is facilitated by means of a cross arm hereinafter described. The quoin is then tightened until it binds block 25 against opposite wall 13 to hold the type form in desired position.

When the structure is to be used in printing advertising circulars, type form 25 bears the entire message as a unit. It is often desired to combine such message with the name and address of a particular dealer. In this case a separate line or more of type 41 is positioned adjacent the top or bottom of type form 25. The extra line or more of type may be held in a small U-shaped frame 42 having spring pressed projections 43 urging type 41 against the adjacent surface of type form 25. The vertical position of the type in the chase 9 is regulated by a cross arm 44 having a guide plate 45 fitting slidably on wall 13. This guide plate also fits over a strip 46 secured to the top surface of wall 13 and bearing indicia to indicate the position of arm 44 so if the cross arm is displaced for any reason it may be reset in the same relative position by reference to the indicia. A pressure plate 47 is positioned adjacent wall 13, and a set screw 48 threaded through one wall of guide plate 45 is tightened against the pressure plate to hold cross arm 44 against accidental movement. j

The type heldin small chase 9 cannot move accidentally in any direction relative to large chase 2 when both quoins 23 and 24 are in their tightened positions. If the line of type 41 is to be removed andreplaced, it may be forced against spring pressed projections 43, and lifted out of frame 42. A new line may be inserted without bothering either quoin or the arm 44. If the type is to be moved only `in a lateral direction, quoin 23 is loosened and chase 9 is moved laterally relative to the larger chase. If the type is to be shifted only in a vertical direction relative to small chase 9, quoin 24 and set screw 48 are loosened.

Cross arm 44 is of slightly less length than type form 25 so that when quoin 24 is tightened it bears evenly against the side of form 25. The cross arm may be moved at any time by loosening set screw 48.

From the foregoing it will be seen that I have provided means for adjustably mounting a small chase within a large chase to eliminate the use of an excessive amount of furniture when a printing press having a comparatively large bed is used for printing a small form. The small chase is provided with efiicient means for rapidly positioning and securely holding a small amount of type in any desired position.

Although I have described a preferred embodiment of my invention in considerable detail, it will be understood that the description thereof is intended to be illustrative, rather than restrictive, as many details of the structure may be modified or changed without departing from the spirit or scope of the invention. Accordingly, I do not desire to be restricted to the exact construction described.
